dc.description.abstractThis paper proposes and illustrates the concept of liquid crystal based tunable optofluidic polarizer. The tunability in the polarization is achieved by allowing the liquid crystal to flow through a rectangular channel at a suitable flow rate for a particular period of time. It is demonstrated that pressure driven flow perpendicular to the director n can induce a reconstruction of the molecular alignment from vertical (V) to horizontal (H) state through several intermediate states and hence the polarization state of the transmitted beam can be changed. Further, the topological changes in nematic liquid crystal molecules under Poiseuille flow are analyzed in detail, employing conoscopy and optical transmittance studies.
